Q: What is Cyclical Redundancy Checking?

A: Cyclic redundancy checking (CRC) is a common technique for detecting data transmission errors. As data rates increase, it becomes more important that data be delivered accurately between SCSI devices. Ultra160 devices utilize CRC to add code, similar to a checksum, to each data transfer. The receiving SCSI device can decode the extra code to verify that the data was transfered accurately.
